feat: Add pattern to demonstrate how to cache large/ML container images to reduce time to start pods

[bryantbiggs]

Description

• Add pattern to demonstrate how to cache large/ML container images to reduce time to start pods

Motivation and Context

• Similar to the Bottlerocket blog and sample repository, this pattern demonstrates how users can create EBS volume snapshots that contain pre-pulled container images. This helps to reduce the amount of time and resources required to pull large container images, reducing the time it takes for pods to start on new nodes (where a cached image exists)

How was this change tested?

• Yes, I have tested the PR using my local account setup (Provide any test evidence report under Additional Notes)
• Yes, I have updated the docs for this feature
• Yes, I ran pre-commit run -a with this PR

Should we publish this under aws-ia?

if someone wants to embark on that saga of an adventure, sure 😅 - but I purposely put it here and not https://github.com/terraform-aws-modules because I suspect (hope) its usefulness declines to nil if better alternate means come to fruition
